Thanks Joe, but one more question. The 6 mm cap nuts, are they the same ones used on the bottom of the engine to attach the oil pan cover? I have always found these easy to strip. But you say you drill them for safety wire... drill straight across near the top, or what?

We have had to replace valve guides in IO520's mounted in the front of
Bonanzas that have those prized GAMI injectors which allow "safe" lean
of peak running. We have to start replacing guides at around 400 to 500
hours; extremely early. We have some that go to TBO with valves and
guides being like new. These were run on the preferred rich side of peak.

Hi Jack. Yes they are the bottom oil sump cap nuts that I drilled at
the top with a 1/16th drill bit. They have to be drilled very close
to the top to clear the top of the 6mm stud. Set the drill press on
slow and fee in slowly using a pecking cycle to avoid catching the
drill bit and breaking it off. Center punch both sides first, and
drill in to the center of one side , turn the nut over and drill
through to the center then go all the way through. You only have to
do four of them. Then drill the edge of the intake flange with four
1/16" holes, to secure the nuts, using a variable speed hand drill.
Go slowly, the little bits break easily. When assembling use never
size and just hand tighten, don't over torque. Then safte wire
with .032 stainless.

HI Gang
I've hired a Bug mechanic to assist me in my over haul. One because I hope
he doesn't have to stop and read the manual all the time and two he should
have all the tools to do it.
Any idea how long it will take to do. I a have the jugs off and ready to
split the case.
